Question

Household bleach is an aqueous solution of sodium hypochlorite. What is the chemical formula of sodium hypochlorite? Is sodium hypochlorite on acid or a base? Prove your answer y chemical reaction between and water. You analyze a solution of sodium hypochlorite using a titration analysis like what we did in lab for vinegar. In that analysis, you found that a 25 mL sample of sodium hypochlorite needed 10.25 ml. of 0.0500 M HCl. Write the chemical reaction between HCl and sodium hypochlorite. How many grams of sodium hypochlorite are in the blench sample?

Explanation / Answer

a) chemical formula of sodium hypochlorite = NaClO

b) sodium hypochlorite is a base.

ClO- + H2O -------------> HOCl + OH-

c)

i) Chemical reaction between HCl and sodium hypochlorite is

2HCl + NaClO ----------> Cl2 + H2O + NaCl
